Dear community, our car has been at the workshop for a few days. It is a guarantee case. Order should last 2 days, but now it takes 1 week. I was given a 5 with a base engine. On request to get an equivalent vehicle, the dealer blocks off. However, after research, I have learned that the right to equivalence exists, i.e. 6s/7. Can someone give me advice? Specifically, it is about an overplay of an older S oftenware on the ECU/Navi. This process has been going on for days. On request, why not just leave the new version on it, the workshop manager replies that this upgrade is subject to payment, as the unlock code has to be ordered. LG Brando
